Based on the data of six main pollutants( PM_(2. 5),PM_(10),SO_2,NO_2,O_3,and CO) and temperature( the maximum temperature and the minimum temperature) in Binzhou City during 2014-2016,the annual and monthly variations in the concentrations of these main pollutants in Binzhou City were analyzed,and the correlations between PM_(2. 5) and other pollutants were discussed using SPSS software. The results showed that the concentrations of PM_(2. 5),PM_(10),SO_2,NO_2,and CO in Binzhou City reduced gradually,while O_3 concentration fluctuated from 2014 to 2016. The concentrations of PM_(2. 5),PM_(10),SO_2,NO_2,and CO in winter were higher than that in summer,while O_3 concentration showed an opposite trend.There was a strongly positive correlation between PM_(2. 5) and PM_(10) concentration,and PM_(2. 5) concentration correlated positively with SO_2,NO_2 and CO concentration,while it correlated negatively with O_3 concentration,the maximum temperature,and the minimum temperature respectively.
